  Abstract

In this work, the eff ects of intra-layer hybridization on the fl exural properties and failure mechanisms of composite laminates were experimentally and numerically investigated. Test specimens were prepared via the thermo-forming technique with plain woven fabrics reinforced using net carbon, glass, and their intra-layer hybrids. The force밺isplacement curves, failure modes, and fl exural properties were analyzed and compared. The experimental results revealed that the catastrophic failure modes of carbon fi ber-reinforced composite laminates can be improved after hybridization with glass fi bers. However, the fl exural properties of the composite laminates, such as fl exural strength and modulus, depended on the type of fi ber along the longitudinal (i.e., load-carrying) direction. A higher fl exural strain can be obtained by replacing the longitudinal carbon fi ber yarns with glass fi ber ones. Subsequently, fi nite element models that considered the inter-layer and intra-layer deformation behaviors were established and validated with the tested results. The maximum error between the experimental and predicted fl exural properties was 6.15%. The fracture process and stress distribution of the specimens were predicted and analyzed to understand the failure mechanisms. Notably, it was observed that intra-layer hybridization critically aff ected the transverse stress distribution state across the thickness of the composites, which resulted in complicated failure behaviors among adjacent fi ber yarns. Finally, the eff ects of interfacial properties on the fl exural responses were simulated and analyzed.
